Epub_Prc_Sp_Code Isolation Procedure; Epub_Prc_Phyp_Code Isolation Procedure - IBM Power System 8335-GCA Manual

Note: If your system is an 8335-GCA or 8335-GTA, go to "8335-GCA and 8335-GTA locations" on
page 111 to identify the physical location and removal and replacement procedure. If your system is
an 8335-GTB, go to "8335-GTB locations" on page 121 to identify the physical location and removal
and replacement procedure.
v If the sensor name is CPU Func 1 or CPU Core Func x, where x is 1 - 12, replace system processor
CPU 1.
v If the sensor name is CPU Func 2 or CPU Core Func x, where x is 13 - 24, replace system processor
CPU 2.
v If the sensor name is Mem Buf Func 1, replace memory riser 1. If the sensor name is Mem Buf Func
2, replace memory riser 2. And so on.
Does the problem persist?
If Then
Yes: Replace the system backplane. If the replacement of the system backplane does not resolve
the problem, go to "Contacting IBM service and support" on page 110. This ends the
procedure.
No: This ends the procedure.
5. The system is an 8348-21C. For each of the SELs that you identified in step 2 on page 96, are any of
the sensor names CPU Func or CPU Core Func x, where x is 1 - 12?
Note: Go to "8348-21C locations" on page 133 to identify the physical location and removal and
replacement procedure.
If Then
Yes: Replace the system processor. Then, continue with the next step.
No: Replace the system backplane. If the replacement of the system backplane does not resolve
the problem, go to "Contacting IBM service and support" on page 110. This ends the
procedure.
6. Does the problem persist?
If Then
Yes: Replace the system backplane. If the replacement of the system backplane does not resolve
the problem, go to "Contacting IBM service and support" on page 110. This ends the
procedure.
No: This ends the procedure.

EPUB_PRC_SP_CODE isolation procedure

A problem was detected in the system firmware.
Update the system firmware image. Go to Getting fixes and update the system firmware with the most
recent level of firmware. Then, reboot the system. If the system firmware update does not resolve the
problem, go to "Contacting IBM service and support" on page 110. This ends the procedure.

EPUB_PRC_PHYP_CODE isolation procedure

A problem was detected in the system firmware.
Update the system firmware image. Go to Getting fixes and update the system firmware with the most
recent level of firmware. Then, reboot the system. If the system firmware update does not resolve the
problem, go to "Contacting IBM service and support" on page 110. This ends the procedure.
